7 Application "filed April '3,

To all whom it may concern: r 1 1 Be it known that I, FRANK HUGO BRAND, a citizen of the United States, and resident of Elmwood Place, in the county of Hamilton and State of Ohio, have invented'certain new and useful Improvements inSt-oves, of which the following is'a full, clear,'and'exart description, reference being had to the accompanying drawings, forming a part of this application. 1

M invention relatesto stoves, and particularly to such as are adapted for the use of gas or oil for fuel.

One of the ol'ijects of my invention is to provide a stove of high eiliciency in the utilization of the heat units of the fuel em ployed, and thus of great economy in open ation.

Another object of said invention is to provide a stove in which the-heat radiationis set up rapidly after the stove is put into operation, which will heat to its maximum capacity in a short period of time, and which, when once fully heated, will retain its heat for a long time, thus permitting further economy of fuel after the stove is heated to the desired temperature.

A further object ofsaid invention is to provide a stove of such construction that, while the heat radiation is unusually great, the outer casing, or shell, of the stove will not become greatly heated, thus permitting the ornamental embellishment of the stove or its coating with white, or other colored enamel, which will not become cracked or marred by reason of too high a tempera ture.

Other objects of my invention will appear from the following description thereof.

In the drawings:

Figure 1 is a side elevation of my new stove;

Fig. 2 is a vertical sectional view thereof;

Fig. 3 is a section on line 3-3 of Fig. 2;

Fig. 4 is an enlarged section on line t 1 of Fig. 2.

The numeral 1 indicates the outer casing, or drum, of my new stove. Said casing is provided at its upper end with an inturned flange 2 having a series of openings 3. The lower end of the drum 1 is arranged to fit within a flange 4: of a base 5. The flange a, just inside the drum is provided with an annular series of openings 6. The flange 1 extends inwardly, as shown at 7, to provide a support for an intermediate drum 8,

which fits inside of, and extends above the flange 2 at the top of the outer drum. Arrangedto lit snugly inside the drum 8 is the combustion chamber drum 9. Secured in thebottom of the drum 9 is a series of grate bars 10, the inner ends of said grate bars being secured to a ring 11. Arranged to lit into the ring 11 is a pipe 12, which extends upwardly approximately to the top of the drum 9, through the center of the combustion chamber. Secured to the pipe 12 is aseries of partitions 18, which serve partlyflto space the pipe from the drum 9, and partly to divide the combustion chamber Into compartments in which fire clay letis piled substantially to the top of the chamber,the said fireclay resting at the bottom:

of the chamber upon the grate bars 10. Arranged to fit snugly into the pipe 12 is a hot air pipe 15, the same extending downwa'rdly through a central opening in the base 5 and upwardly a considerable distance above the drums 8 and 9, as clearly shown in Fig. 2. The pipe 15 is supported on the base 5 by means of a collar 16 on the pipe. A short distance below the grate bars 10, the pipe 15 is provided with a second collar 17, which serves as a rest for the gas or other burners 1S and 19, concentrically arranged; The burners are supplied'with fuel by pipes 20 and 21 from a main supply pipe 22.

' Arranged to fit over the top of the drum 8 is a cover 23, the outer flange of said cover extending down around the outer side of the drum 8 and contacting with the flange 2 of the outer drum. The cover has a central opening surrounded by a downwardly extending flange 24. In the assembly the flange 24 extends downwardly between the pipes 12 and 15, as clearly shown in Fig. 2, thus preventing the escape of the fumes of combustion between the pipe 12 and said flange 24. For the purpose of carrying off said'fumes the cover 23 is provided with a line opening in its top communicating with a pipe 25.

Arranged to fit down into the hot air pipe 15 is a vapor pan 26, the same being sus pended in the pipe by hangers 27. As will be seen neither the pan nor the hangers materially, interfere with the upward circulation of heated air through the pipe 15.

The combustion chamber is lined with asbestos to the height of the flames, as shown at 83, and a similar lining 34, is given to the inside of the outer drum 1, thus insulating it and preventing the overheating of the outer surface of the stove and permitting it safely to be provided with a coating of enamel.

The stove as above, described is set into an ornamental base 28, being supported'thereon by means of a flange 29Von the outer drum of the stove. An ornamental top 30 is also provided, when desired, the same resting on the upper portion of the drum 1, as shown. Said top is provided with openings 31 through which currents of heated air may ascend. The base 5 and ornamental base 28 are provided with suitable openings 32, through which the burners may be observed for regulation of the flames, in the usual manner. 7 a

The nature and operation of my new stove will be apparent from the foregoing.

description torthoseskilled in the art to which the same appertains. When the gas at the burners 18 and 19 has been ignited,

there will be a very rapid heating of the hot air flue 15, and a current of hot air will thus almost immediately be set up in said flue, ascending past the vapor pan and being discharged into-the room to be heated. As the flames continue, the fire clay in the combustion chamber will become heated as will also the intermediate drum 8; a current of hot air will thus be set up in the space between the outer and intermediate drums, the cold air entering at the openings 6 in the base and H the drums 1 and 8 being maintained by the reduced flame and the heat stored in the clay'. i

It will be understood that various modifications may be made in the details'above described without departing from the principle of my said invention, and I therefore desire to have it understood that I consider all such modifications as within the scope of my invention as .fall fairly vwithin the purview of the appended claim.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:'. V

A. stove comprising an outer drum, having an inturned flange at its upper end; a base, said base having a flange arrangedto engage said drum; air passages in the flanges of said drum and base; an intermediate drum arranged to rest upon said base'and to fit snugly in and to extend above the outer drum flange so as to leave a passage between said drums; a third drum fitting snugly inside said intermediate drum grate bars for the support of fire clay inthe bottom of said third drum; a ring for securing the inner ends of said bars; a pipe arranged to fit inside said ring and to extend through said third drum so as to leave a combustion chamber between said pipe and third drum; burners arranged at the bottom of said combust-ion chamber; a cover arranged to fit over said combustion chamber; a flue in said cover'; a hot air pipe fitting snugly in said first pipe and arranged to extend through and above said cover, and an ornamental top, said topbeing provided with a central passage for said hot air'pipe and with openings arranged to serve as outlets for air currents from the passage between the outer and intermediate drums.
